The extraction of boron from treated wood for quantitative analysis: A comparison of procedures
1992 - IRG/WP 92-2414
The extraction of boron preservative from treated rubberwood and scots pine samples was compared using methods based on refluxing and extraction in 1N NaOH or distilled water at 80°C. The extract solutions were analysed by Inductively Coupled Plasma spectroscopy (ICP/AES). A simple extraction procedure based on immersion of wood samples of approximate dimension 2 x 1 x 1 cm³ in distilled water a...
